Geomembrane yopangidwa ndi HDPE imapangidwa ndi polyethylene yochuluka kwambiri (HDPE) ndi wosanjikiza wa zinthu zapadera za geotextile composite. Amagwiritsidwa ntchito ngati zodzipatula komanso zodzitchinjiriza m'magawo monga uinjiniya wosungira madzi, uinjiniya wamisewu, uinjiniya woteteza zachilengedwe, komanso uinjiniya wokonza malo.
Mtundu uwu wa geomembrane uli ndi zinthu zambiri zabwino kwambiri. Choyamba, ili ndi kusasunthika bwino komanso kukana dzimbiri, zomwe zimatha kudzipatula ndikuteteza nthaka ndi matupi amadzi, kusunga bata ndi chiyero cha chilengedwe chamadzi. Kachiwiri, geomembrane yamtundu wa HDPE imakhala ndi mphamvu zolimba kwambiri komanso kukana misozi, ndipo imatha kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta popanda kuwonongeka kapena kukalamba. Kuphatikiza apo, imakhala ndi kutentha kwambiri komanso kuzizira kozizira, ndipo imatha kugwiritsidwa ntchito m'malo otentha komanso otsika kwambiri popanda kukhudza mtundu wazinthu.

Zochitika zogwiritsira ntchito ndizokulu kwambiri, monga kugwiritsidwa ntchito ngati makoma osasunthika, zitsulo zamadamu, mizati yosasunthika, nyanja zopangira, malo osungira madzi onyansa, ndi zina zotero mu zomangamanga zosungira madzi; Muumisiri wamisewu, atha kugwiritsidwa ntchito ngati gawo lodzipatula la msewu, geotextile, ndi zina; Itha kugwiritsidwa ntchito ngati dothi lolowera m'nthaka muukadaulo wazachilengedwe, ndi zina; Mu engineering landscaping, itha kugwiritsidwa ntchito ngati udzu, gofu, ndi zina zotero.
Mwachidule, HDPE composite geomembrane ndi chida chabwino kwambiri chodzipatula komanso chitetezo chokhala ndi mtengo wogwiritsa ntchito komanso chiyembekezo m'magawo osiyanasiyana.

Kodi mafotokozedwe ndi makulidwe a HDPE geomembrane ndi chiyani?

Mafotokozedwe a HDPE geomembrane akhoza kugawidwa mu mtundu wa GH-1 ndi mtundu wa GH-2 malinga ndi miyezo yokhazikitsidwa. Mtundu wa GH-1 ndi wa polyethylene geomembrane wamba wochuluka kwambiri, ndipo mtundu wa GH-2 ndi wa polyethylene geomembrane wokonda zachilengedwe.
Mafotokozedwe ndi miyeso ya HDPE geomembrane akhoza makonda, ndi m'lifupi mamita 20-8 kupanga. Kutalika nthawi zambiri kumakhala mamita 50, mamita 100, kapena mamita 150, ndipo mukhoza kusinthidwa malinga ndi zofunikira.
Makulidwe a HDPE geomembrane akhoza kupangidwa pa 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, ndi wandiweyani akhoza kufika 3.0mm.
